Application filed June 21, 1909. Serial No. 503,332.

a device attachable to a car truck for cutting a furrow parallel to thetracks, for the purposes hereinafter specified, and to provide simpleand durable construction and assemblage of the co-acting members forsecuring facility of operation and etliciency of action. These objectsare attained in the following described manner as illustrated in theaccompanying drawings, in which Figure 1 is a plan of a grass and ditchline cutter embodying my improvements; Fig. 2, a rear elevation; Fig. 3,a vertical section on the line a-a of Fig. 1 showing the hook and stapleconnection of the brace rod with the truck, and Fig. l a horizontalsection showing the manner of connecting the furrow opener with theextensible arm.

In the drawings, 1 represents a railroad track, 2 a track or hand carmovable thereon and provided with hinge members 3 and 4-. A tubular arm5 is removably hinged at one end to either of the hinge members 3 bymeans of a removable pintle or bolt 6. A shaft 7 secured in difierentlongitudinal and also different rotative adjustments within the arm 5 bymeans of a set screw 8 is formed with a collar 9 and with a spindle 11at a slight angle to its length. A concavo-convex disk or furrow opener12 provided with a hub 13 on its concave side is rotatively mounted onthe spindle 11. A nut 14 adjustably threaded on the end of the spindleand concealed within a counter bore 15 formed in the hub serves tomaintain the disk in proper position on the spindle without anyextension beyond the convex surface thereof. A brace rod 16 movablyconnected at one end near the outer end of arm 5 is formed on itsopposite end with a hook 17 adapted to detachably engage with either ofthe staple or hinge members 4 as desired. A handle 18 secured near theouter end of arm 5 is a convenience for the operator in controlling thepressure on the disk or for raising it over 0bstructions.

In operation, the truck may be moved slowly along the track for causingthe disk.

to cut a line in the soil parallel to the track and at such apredetermined distance therefrom as the extensible connections of thedisk with the truck may be adjusted and secured.

By means of the rotative adjustment of the shaft in the arm, the diskmay be adjusted in different vertical and horizontal anglessimultaneously in relation to the arm, for regulating the amount of itsshearing cut and for better adapting it to operate at differentelevations in relation to the track.

The hinge connections with the truck permits the disk to be raised orlowered by means of the handle or to be turned directly over the truckfor being moved short distances. The disk and connections may beentirely disengaged from the truck when de* sired by the removal of thepintle 6 from hinge 8 and the disengagement of hook 17 from staple a,and it may be attached to either side of the truck as desired.

Having fully described my improvements, what I claim as my invention anddesire to secure by Letters Patent of the United States is In a grassand ditch line cutter, the combination with a truck adapted to run on atrack, a tubular arm removably hinged at 7 one end to the rear portionof one side thereof, a brace rod secured to the other end of the arm,and removably hinged to the front portion of the same side of the truck,and a handle secured on the arm whereby a downspecified.
